“…Rhabdias elegans Gutierrez, 1945, known from various anurans, mostly bufonids, in the southern parts of South America (Gonzáles & Hamann, 2009; Kuzmin et al ., 2015), differs from R. glaurungi sp. nov. by its larger body size (4.55–9.5 mm long, after Kloss, 1974).…”

The genus Rhabdias Stiles & Hassal, 1905 includes about 83 species of nematodes parasitic in amphibians and reptiles worldwide. Herein, we describe Rhabdias glaurungi sp. nov. from the hylid frog Scinax gr. ruber (Laurenti, 1768) in the Gunma Ecological Park, Santa Bárbara municipality, state of Pará, Brazil. This species has six small lips, an inflated cuticle along the entire body and a cup-shaped buccal capsule with smooth internal surface of its anterior part and irregularly folded internal surface of its posterior part in apical view. From the 17 valid species recognized in the Neotropical realm, the new species can be distinguished by the number of lips, the morphology and size of its buccal capsule, as well as the extent and shape of its cuticular inflation; in addition, there are molecular differences. Sequences of the mitochondrial Cytochrome c Oxidase subunit I gene strongly support the status of this form as a separate species. Molecular phylogenetic analysis shows R. glaurungi sp. nov. nested within the R. pseudosphaerocephala Kuzmin, Tkach & Brooks, 2007 species complex. Rhabdias glaurungi sp. nov. is the second species of the genus described from hosts of the family Hylidae in the Neotropical realm. We conclude that the diversity of Rhabdias within the Neotropics is likely largely underestimated.

Here, we describe a new kathlaniid nematode, Falcaustra sanjuanensis sp. nov., from the large intestine of Odontophrynus cf. barrioi (Anura: Cycloramphidae), from San Juan Province, Argentina. The new species belongs to the Falcaustra group that possesses a pseudosucker. It resembles F. andrias in the distribution pattern of caudal papillae (six precloacal, four adcloacal, 12 postcloacal, one unpaired median anterior to the cloaca) but differs from F. andrias in the following characters: the longer size of males and females (11.17-13.45 mm and 10.1-15.5 mm, respectively); the longer size and form of the gubernaculum (0.17-0.23 mm, triangular form); the arrangement of postcloacal papillae (three pairs on the ventral side, two pairs on the lateral side, one pair on the subventral side) and unpaired papilla anterior to the cloaca located on the protuberance. The species description is based on light microscopy and scanning electron microscopy (SEM). Falcaustra sanjuanensis sp. nov. represents the 12th Neotropical species assigned to the genus. Also, we added a key to Neotropical species of Falcaustra.

“…Los cosmocercidos, son parásitos comunes del intestino de anfibios y reptiles, presentan ciclos de vida directos (monoxeno) y las larvas infectantes ingresan al hospedador por vía oral (Aplectana) o a través de la piel (Cosmocerca) (Anderson, 2000). Previamente han sido hallados cosmocercidos de estos géneros en numerosas especies de anuros neotropicales, incluyendo varias del nordeste argentino, entre ellos Pseudopaludicola falcipes, Rhinella major, R. fernandezae, R. bergi, R. schneideri, Leptodactylus bufonius, L. chaquensis, L. latinasus, Physalaemus santafecinus, Scinax nasicus, S. acuminatus, Odontophrynus americanus, Dendropsophus nanus, D. sanborni e Hypsiboas raniceps (Mordeglia y Digiani, 1998;González y Hamann, 2004;, 2006bHamann et al, 2006aHamann et al, , 2006bGonzález y Hamann, 2007;González y Hamann, 2008;González y Hamann, 2009a, 2009bHamann et al, 2009;González y Hamann, 2010;González y Hamann, 2011).…”

Resumen. Diversos aspectos de la historia natural de especies del grupo Leptodactylus marmoratus son escasamente conocidos y la poca información existente aborda principalmente los de la biología reproductiva. El objetivo de este trabajo es aportar información acerca de la dieta y del parasitismo de poblaciones de Leptodactylus diptyx del nordeste argentino. Para el estudio trófico, se analizó el contenido estomacal e intestinal de 22 individuos adultos, mientras que para el estudio parasitario, se examinó el tubo digestivo de 40 individuos. Se registró un total de 91 presas, clasificadas en 17 categorías, entre los cuales los himenópteros formícidos fueron los más numerosos (45%) y frecuentes (55%). Otras presas importantes fueron colémbolos, coleópteros y arañas. Los valores de diversidad de presas (índice de Shannon) y amplitud del nicho (índice de Levins) fueron 2.06 y 4.29, respectivamente. El 57.5% de los individuos examinados resultó positivo al examen de endoparásitos, entre los que se incluyen nematodos y acantocefalos. Leptodactylus diptyx representa un nuevo hospedador para los nematodos Cosmocerca sp. y Aplectana sp.
